Chain will not move on chainsaw
This will be the basic instruction for most common
saws. Check that the chain brake is in disengaged position by moving the front
hand guard towards the front handle if the saw is equipped with a chain brake
on the handle. Loosen the bar nuts on the clutch cover. Loosen tension screw or
other adjuster (thumbscrew) to allow the bar to be moved toward the engine.
Some saws have this tension adjustment built into the bar. This will provide
enough slack in the chain to able to reinstall it. It may be necessary to
remove the side cover to gain access to the clutch/gear assembly on the side of
the engine if the chain also jumped the gear here. Remove the cover, inspect
for any debris or other obstructions in this area. If none, replace the chain
back over the drive gear and in the bar groove all the way around the bar. It
may be necessary to turn the bar adjuster screw more to provide enough slack in
the chain to do this. Once the chain is in place reinstall the cover and bar
lock nuts. Snug up the nuts but do not tighten these. Turn the bar/chain
adjuster screw to tighten the chain on the bar (take up slack). I usually
tighten to a point where there is no slack between the chain and the bottom of
the bar and I can still turn the chain easily around the bar by hand. With
experience you will get the feel for this chain tension. Once the chain is
properly tensioned, tighten the bar lock bolts/ nuts on the side cover.
Some Poulan Pros have an adjuster screw on the front of the engine case right beside the bar, some have a tool less adjuster on the clutch cover, and some have a slot in the bar for adjusting the chain tension.
this helps you out.
